MEDAL FOR BEST ANSWER
Solve for x: -3|x + 7| = -12

anonymous · Answer

divide -3 on both sides then tell me wat u get

anonymous · Answer

-11?

anonymous · Answer

-3|x + 7| = -12
$$|x + 7| = \frac{-12}{-3} \rightarrow  |x + 7| = 4$$
$$ x + 7 =  \pm 4$$
i.e. $$ x + 7 =  4$$ or  x + 7 = - 4
i.e. x= 4-7 or x= -4-7
i.e. x= -3 or x= -11 is the required answer.

no i just said to divide by -3 on both sides not to solve the whole problem

anonymous · Answer

i wanted to see if u knew how to work the problem just not to give u the answer

anonymous · Answer

we can simply do  -3|x + 7| = -12
|-3x-21|=-12
3x+21=-12 asafter retriving any value from modulas the sign is changes to positive
x=-12-21/3
x=-11
